This high availability solutionprovides fault tolerance against a single point of failure caused bya hardware component. Redundant hardware must include twoseparate Fibre Channel paths, including two servers, two HBAsin each server, two switches, two MSA I/O modules, two MSAcontrollers, and the duplicate cables needed to connect thesedevices.Several multipathing failover options are supported for use withthe MSA1000/MSA1500 cs, including the basic options and theadvanced support delivered with the optional purchase of HPStorageWorks Secure Path multipathing software.Basic multipathing failover benefits include:■ No additional cost■ Simple update to the operating system/HBA driver■ Automatic failover■ Notification and status messages automatically written tosystem event logs and the MSA controller LCD displayThe basic failover methods work best in relatively simplemultipath environments; complex multipath environments maybenefit from a more advanced solution, such as that provided bySecure Path.For environments already using Secure Path, no action isrequired. There is no need to convert to this more basic level offailover management.Note: In addition to the multipathing information included in thisdocument, refer to information available under the keyword “MPIO”on the Microsoft web site: http://www.microsoft.com.Prerequisites■ Basic multipathing solutions can not co-exist with any othermultipathing solution, such as Secure Path or AutoPath.If other failover methods are currently installed in yourenvironment, HP recommends making no change, and tocontinue using that method.If you choose to migrate to the basic failover method, youmust first un-install all other multipathing software from yourservers.■ The MSA must be installed in a supported environment, asdetailed in the MSA Compatibility Guide and QuickSpecs.Review these documents on the MSA web sites:MSA1000 http://www.hp.com/go/msa1000MSA1500 cs http://www.hp.com/go/msa1500cs
